The Jackal (1997)
How do you stop an assassin who has no identity?
Hired by a powerful member of the Russian mafia to avenge an FBI sting that left his brother dead, a psychopathic hitman known only as The Jackal proves an elusive target for the people charged with the task of bringing him down: a deputy FBI director, a Russian MVK Major, and a jailed IRA terrorist who can recognize him.
